The following information is pertinent to W.A users, I don't know how much it would correlate with other states.
The Smilies/Rainbow Smiley tabs are real nice, they certainly feel like a clean shot of acid but a relatively low loading, untested on ehrlich's.
Chromosones and Third Eye tabs are both DOET (substantiated on NMR, negative to ehrlich's) and have a very unpleasant body loading.
There's been a few batches of 'Purple Ohms', the most recent that came out over the last weekend at the doof were remarkably powerful but definetly not LSD, they felt a lot like DOI and were negative to ehrlich's.
'Pharoah' tabs are a decent loading of straight up LSD, real nice tabs those ones, positive to ehrlich's.
Where's Wally/Rollercoaster Tycoon (same tab but named different things) aren't as strong as the Smilies but are real smooth.
'Rolling Stones' or 'Forty Licks' tabs are clean but WEAK AS PISS. Like, no shit, two tabs had only mild visuals after 2 hours and some weed, estimated loading about 30-60ug per tab, weak positive on ehrlich's.
'Pink Heart' tabs are very nice, untested but very powerful.
'Alien Head' tabs I haven't seen for a while now but still pop up occasionally and are wickedly strong.
There's some liquid flying around, amber solution, positive on ehrlichs and still waiting for an NMR result. Very potent stuff by the feel of it, probably about 250ug-450ug per drop.
I was lucky enough to get my hands on some 'Steal your Face' tabs about a month back, a ten spot that a mate had brought backf rom international travels, very powerful, 450ugs at least, but I haven't seen any circulating widely in the scene.
